Embodiment Construction

[0013] The following examples will help to understand the present invention, but do not limit the content of the present invention.

[0014] Firstly, the polyester fabric is irradiated with ultraviolet laser, and the laser wavelength used is λ 1 and lambda 2 It is two different excimer lasers with a wavelength between 180-370nm, and the pulse width of the laser is 20-40ns. Processing devices such as figure 1 , the energy density of the laser is 50~150mJ / cm 2 , the size of the laser spot is 4 mm × 6 mm, the polyester fabric is made of DTY, the treatment area is 12 cm × 6 cm, and the number of irradiations is 5 to 10 times. The rotating speed of the motor used on the working platform is 200 rpm, and the entire processing area is scanned sequentially through the translation of the working platform. After being irradiated by excimer ultraviolet lasers with different wavelengths, the polyester fabric surface has a regular undulating structure, which forms a periodic undulating ...

Abstract

An ultravilet laser method for improving the dyeing property of cationic dye on polyester fabric, especially the terylene, features that the surface form and function groups of polyester fibre are changed by the ultraviolet excimer laser to generate the periodical wave structure for high dyeability.

Description

technical field [0001] The invention is an invention for changing the dyeing performance of polyester textiles, that is, a method for changing the dyeing performance of cationic dyes of polyester textiles by ultraviolet laser. The feature of the invention is a treatment method for changing the surface morphology and surface groups of polyester textiles through excimer ultraviolet laser to obtain the dyeability of cationic dyes. It is especially suitable for polyester fabrics, which can increase the range of dyes used for such fabrics. The ultraviolet laser irradiates polyester textiles, forming periodic undulating structures perpendicular to the fiber axis on the fiber surface in the textiles. This phenomenon also has great scientific value in the study of the interaction between laser and polymer materials. Background technique [0002] Polyester textiles are widely used in industrial and agricultural production and people's daily life. Due to the lack of groups that can ...
